1. Common conversions in biochemistry (I)
1 gram (g) = 1X103 miligrams (mg)
1 gram (g) = 1X106 micrograms (μg)
1 gram (g) = 1X109 nanograms (ng)
1 gram (g) = 1X1012 picograms (pg)
Deal with conversions. I don t know how many from you know these conversions so we will start from the very basic stuff. Some of you know this I am sure, others less...so we will pass through it. When you do conversion from bigger units to smaller units the number on the tenth is always positive.Bigger units olready contain smaller

2. Common conversions in biochemistry (II)
1 miligram (mg) = 1X10−3 grams (g)
1 microgram (μg) = 1X10−6 grams (g)
1 nanogram (ng) = 1X10−9 grams (g)
1 picogram (g) = 1X10−12 grams (g)
The number on the tenth is the same but negative this time beacuse we convert from smaller units to bigger...if they are smaller it is logical that they do not contain the bigger units

3. Exercises (I) How many grams are there in 0.22 μg? 560 ml has ___μl???
0.5 grams is equivalent to how many mg?  
0.56 liters equals how many ml?

before we start dealing with solution we must make some exercises!
560ml koliko mikrolitara560x10na3; 0,22x10na-6; 0.5x10na3; 560ml; 1ml; 1x10na-3; 1x10na3; 0,1;
